Subject: [PATCH] CUSTOM_ID as section label in latex export
When exporting to HTML, custom ids of headlines become references to
the resulting section in the exported document. This is both more
stable and more readable than using section numbers. This commit adds
this option to the latex exporter.
* lisp/ox-latex.el (org-latex-headline): If headlines have the CUSTOM_ID
property set, then this value is used as the label instead of the
section number.
